It is cultivated as an ornamental plant.[4] This species is a perennial herb or subshrub generally growing 10 to 20 centimeters tall, sometimes reaching half a meter. The hairy stems have oppositely arranged leaves. The leaf blades are leathery in texture and oblong or lance-shaped. They measure up to 12 centimeters long. The inflorescence is a narrow spike up to 60 centimeters long. The flowers come in many shades of red and pink.[4] This species sometimes escapes cultivation and becomes established in the wild. It can be weedy, growing in disturbed habitat such as pastures and roadsides.[4] This plant is an introduced invasive species in Fiji, Hawaii, Queensland, and Singapore.[4] The flowers are attractive to a variety of insects. The butterflies Ornithoptera priamus poseidon and Papilio ulysses have been observed foraging on the plant, as has the bee Amegilla sapiens.[5] Parts of the plant contain the iridoid glycoside ipolamiide, which inhibits insect predation on the plant.[6] {{Commons category|Stachytarpheta mutabilis}}References1. ^{{cite web |url=http://www.theplantlist.org/tpl1.1/record/kew-195949 |title=The Plant List: A Working List of All Plant Species |accessdate=25 September 2015}} {{Taxonbar|from=Q7595918}}2. ^Stachytarpheta mutabilis.
